SPECIFICATION forming part of Letters Patent No.661,286, dated November 6, 1900.

Application liled May 7, 1900.

To (all whom t may concern:

Be it known that I, CHARLES E. CoL'roN, of Syracuse, in the county of Onondaga, in the State of New York, have invented certain new and useful Improvements in Sewers, of which the following is a specification.

My invention has for its object the production of a sewer which is particularly strong, is readily and cheaply man ufactured and laid, and is so constructed that liability of the spreading' of its base, the outward movement or spreading of its side sections adjacent to said base, and the passage of Water through said side sections is reduced to a minimum; and said invention consists in the combinations and constructions hereinafter set forth.

Figures l and 2 are, respectively, end and side elevations of a portion of a sewer embodying my invention.

My improved sewer consists, essentially, of sections A B C D E F, constructed, preferably, of vitrilied hollow tile. The sections A B and the lower parts of the sections C form the base of the sewer, said sections A B being usually provided with flattened faces of considerable width for distributing the weight of the sewer over a comparatively large area. The sections A form intermediate base-sections and are here shown as each provided with a longitudinal upper portion or extension c, of less width than its lower portion, shoulders d extending laterally from opposite sides of the base of the portion or extension a,and side surfaces CL2 diverging downwardly from the outer edges of the shoulders d. Said sections B form side base-sections, are arranged on opposite sides of the sections A, and are here illustrated as having the inner portions of their upper faces b disposed substantially coincident with the shoulders a and as formed with downwardly -diverging side surfaces Z2', engaged with the surfaces a2. The outer portions of the upper faces of the sections B are generally provided with upward extensions b2, having upwardly-diverging inner faces and upwardlyconverging outer faces. The sections C diverge upwardly in opposite directionsfrom the intermediate base-sections A, are supported partly upon the shoulders d of the sections A and partly upon the inner portions of the upper faces b of the sections B between the extensions ?)2 of the sections B and at opposite Serial No. 15,695. (No model.)

sides of the portions or extensions d of the sections A, and are shown in the accompanying drawings as having their inner faces engaged with opposite sides of said portions or extensions d and their outer faces engaged with the inner faces of the extensions b2 of the sections B. The arrangement of the sections C between the extensions b2 a obviously prevents either inward or outward movement of said sections C.

In the preferable construction of my invention the upper parts of the sections C just described and the sections D E F form the opposite sides and the top of the sewer. Said sections D E rise one above the other, forming opposite sides of the base of the sewer, the lowermost sections D being supported partly upon the sections B and partly upon the sections C and being provided with depending extensions (l, engaged with outer faces of the extensions b2. The inner portions of the lower faces of the sections D E are formed with depending arms d e, said arms d of a number of the sections D having their lower faces clzinclined down wardlyfrom the inner edges d thereof and the upper edges Z4 of their outer faces arranged above said inner edges. The 'outer portions of the upper faces of the sections C D are provided with upwardly-projecting arms c d5, having their inner faces engaged by the arms d e, and the inner portions of said upper faces are formed with cut-outs c d, which receive the arms d e and form said outerarms c di. The engagement of the depending extensions d of the lowermost side sections D with the upward extensions b2 of the side base-sections B prevents spreading of the base-sections, and the arrangement and construction of the arms d c d5 and the cut-outs c d6 as described prevent outward movement or spreading of the lower ends of the side sections D. Oonsequently when the sewer is completed the base and side sections are not liable to move from their predetermined po* sitions. The sections are readily laid in position, even by unskilled workmen, without the necessity of supporting-frames, and the sewer is rendered more strong and durable than would otherwise be the case. Moreover, the passage of water through the walls of the sewer is reduced to a minimum by so form- IOO ing a number of the arms CZ that their lower faces d2 incline downwardly from their edges d3 and that the upper edges d4 of their outer faces are above said edges cl3. It is obvious, however, that said arms d' may be otherwise constructed, if desired. The upper faces of the sections E and the opposite sides of the sections F converge downwardly, said sections F forming a key for the sections E E.

The construction and operation of my sewer will now be readily understood upon reference to the foregoing description and the accompanying drawings, and it will be obvious to those skilled in the art that more or less change may be made in its component parts without departing from the spirit of my invention. i

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a sewer, the combination of a base, opposite side sections rising` from the base, and having the outer portions of their upper faces provided with upwardly projecting arms, and additional opposite side sections resting on the former side sections and having the inner portions of their lower faces provided with depending arms engaging the inner faces of the former arms, substantially as and for the purpose described.

2.

3. In a sewer, the combination of base-sections provided with upward extensions, additional sections engaging the upper faces of said base-sections and the inner faces' of the extensions, and side sections engaging outer faces of the extensions for preventing spreading of the base-sections, said side sections also engaging the additional sections, substantially as and for the purpose set forth.
